I haven't found an electric that will shave all my hair. They seem to like to catch a little bit, but move most of it to the side, instead of cutting it. With Norelcos, which seem to work the best, the lift-and-cut action hurts like Hell, as well, causing a different kind of irritation compared to my non-electric shaving, yet still laves about half untouched, no matter how many passes I make. Other kinds cut more, but don't cut as close, or very evenly, and still leave whole patches almost untouched.
There also isn't any particular difference in the effectiveness of various multiblade razors. If I really must shave close, I'll use unscented Dr. Bronners, and a 2-blade disposable. If I shave like that for a few days, it gets bad. Thick stubble, bumps, ingrown hairs, etc.. Store-bought shaving creams and gels just end up irritating my skin, or having a fragrance or oil I'm allergic to.
I figure that, one of days, I'll have to take the time to learn to use the old fashion kind.
